Crude chitinase which produced by Trichoderma virens UKM-1 in Trichoderma Minimal Medium (TMM) was used for enzymatic degradation of crude prawn waste. Optimization of prawn waste degradation process was conducted using 2.0% (w/v) crude prawn waste concentration yield chitin degradation rate of 60.76% (w/w). The optimum degradation temperature was 50ºC resulting in the degradation rate of 60.38% (w/w). Crude prawn waste degradation in agitated system enhanced chitin degradation rate up to 75.56% (w/w) indicating a total degradation rate improvement of 1.69 fold. Degradation of pre-treated prawn waste produced various types of chitooligochitin and N-acetyl-glucosamine (NAG). Partial characterization was carried out on the crude chitinase produced by T.virens. The best buffer for chitinase activity was citrate-phosphate buffer with optimum pH 4. Chitinase activity was stable as pH increases to pH 7.0. Optimum temperature for crude chitinase was found at 50ºC but its stability decreases as temperature exceeds 50ºC. Six protein bands were visualized for induced sample. The crude chitinase protein sizes were identified as 73.0 and 64.0 kDa (N-acetyl-β-D-glucosaminidase); 46.0 and 37.0 kDa (endochitinase); 28.0 kDa (exochitinase) and 18.8 kDa (protease). In uninduced protein sample, only one protein band was visualized at 14.4 kDa and was identified as lysozyme.
